Cutting through the controversy about helmet effectivenessAnalysis by Piet de Jong shifts the focus of the helmet debate onto the arguments about the degree to which the large health benefits of cycling outweigh the far smaller risks involved. de Jong uses mathematical modelling to show that even under the most optimistic predictions of helmet benefit, the net public health outcome of helmet promotion (or laws) is negative.

Alcohol: obscuring the outcomes of helmet research?Could many of the predicted benefits of cycle helmets be more accurately attributed to staying sober, as links between drinking and serious injury become clearer? It just so happens that most drunk cyclists don't wear helmets.
